NJU6053 - JRC

NJU6053 White LED Driver

The NJU6053 is a white LED driver with an automatic dimming control. It contains an output driver, a PWM controller, a luminance sensor control (power supply for sensor & A/D converter), a step-up DC/DC converter, a serial interface, etc. The NJU6053 can turn three independent lighting circuits on/off separately or simultaneously with instruction. The output.
